Now might be a good time to explain how No 11 is powered.
She's certainly large enough to be live steam...But she's not.
I lack both the skill and the capitol to do real live steam.
So, as is common to most model railroad locomotives, ours is powered by electricity.
But unlike most model railroads there's NO TRACK POWER, DCC or otherwise.
Our engine is powered by two, on-board, 12 volt marine batteries in series for 24 volts DC.
Lift off the tank cover and this is what you see.
This picture predominantly shows the batteries but also notice the red arrow pointing to the solid state power regulator,
and the green arrow pointing to the on-board battery charger which has it's own 120 volt cord to plug in for charging (over night).
Think of our engine as a steam locomotive simulator.
The engineer controls the locomotive from inside the cab,
using controls which as closely as I can muster simulate actual steam locomotive controls.
In this view we see the throttle (red arrow).
What the throttle actually does is rotate a potentiometer (blue arrow) in the low power control circuit.
Pull it back and the power control module sends battery power to the drive motor and down the track you go.
